Checklist for ALMA optimized imaging workflow:
- Determine when there is a new image dataset to review (how will this be done without the workflow manager - DAs to check for new products directories??)
- In the pilot, only channel widths and ranges can be set, so QA should be focused on those, along with general QA issues:
- Was the restoration of the calibration successful?
- Does the cube as made cover the region of interest requested by the PI (in the PPR). If large parts of the cube are blank, and/or a line is cut off at the edge of the cube the DA should consult with the PI by initiating a helpdesk ticket.
- Does the rms noise in a line-free channel match the theoretical estimate from the pipeline (to within 10% for bands 3-6, 15% for bands 7-8 and 20% for bands 9-10)?
- Are there artifacts in the image suggesting that target flagging is needed? If so, flag the data and rerun the PPR.
- Is the continuum subtraction satisfactory? If not, should iteration be done with user, or should DA pick new continuum ranges for fitting?
